BTUs per 1 gallon of Liquid Propane Gas

There are 91,000 BTUs (British Thermal Units) per each gallon of Liquid Propane (LP) gas.

Depending on which model gas tankless water heater you have that is running off LP gas you could get a close estimate on the amount of LP gas that would be consumed on a daily basis.

For example:
If you had a Bosch 1000P LP gas tankless water heater that has a maximum potential to deliver 74,900 BTUs at its highest fire you could calculate the usage of gallons per minute (GPMs) versus the BTU usage at that rate of burn and get the amount of time it would take to use 1 gallon of LP gas.

Say you run the 1000P LP gas tankless water heater 1 time a day just for a shower. The shower flows exactly 2 GPMs so the tankless water heater would be running at about 74,000 BTUs during this time and then figure on an average you stay in the shower for 10 minutes total time so overall you would burn about 1 gallon of LP gas for every 7-8 showers.

These calculations would vary depending on consistent flow and water pressure, length of time the water is running, the temperature outside will have an effect on the tank and gas pressure and also what BTU the heater is running at that time.

Basically this is an estimate for calculating usage of LP gas with a gas tankless water heater. This data is for example only and will hold no bearing on any Bosch tankless water heater as they all vary in BTU usage.

Descaling Powerstar AE-115 & AE-125

The electric tankless water heaters, Powerstar models AE115 and AE125 are high kilowatt electric tankless heaters that heat water on demand as the water passes through them. The modules inside consist of coiled elements that heat the water. The heating elements produce extreme heat inside the modules to heat the water on demand.

The heat that is produced by the heating elements in the modules sometimes counteracts with the mineral deposits in the water. If there is a high mineral content due to a hard water area then these mineral deposits known as "scale deposits" will over time attach themselves to the heating coils inside the modules.

All Bosch Powerstar electric tankless water heaters should never be descaled with any type of solution such as vinegar, muriatic acid, etc. The use of descalants flushed through the heater does not have much effect on the mineral deposits attached to the elements. Another point of trying to flush descalant through an electric tankless heater is that it will loosen some of the mineral deposits in the heater and will have a damaging effect on the flow transducer and other parts inside the tankless heater that detects the flow of water and will interrupt the signal to the circuit board itself.

The best protection against mineral deposits (scale) forming on the coils in the electric tankless heater is to check the quality of the water in your area before installing and if the water has a high mineral content then it is recommended to install a water softener or scale stopper system. The water softener or scale stopper will filter out almost all of the minerals and treat the water so the electric tankless water heater will have a longer life with less minerals building up inside.
